Default Box build question

I have 4 hifonics Brutus 12's BRZ12D4
Need 1.5 volume per sub
.12 is the displacement of each
The box dimensions are:
3/4" MDF
38.5"L X 26.5"D X 16.5"H
Subs fire up with it chambered behind
The subs so the downforce will fire
Down them back then angled down
Again then another chamber the same
Way on its way out. So 2 additional
Boards 3/4" thick 37"L X 21"D
With a chambered vent of 3.25" all
The way through.
Could anyone tell me if I'm even close
To the correct air space?
